<h3 id="rationale">Rationale:</h3>
<p>ShellCheck has noticed that you reference a variable that is not
assigned in the script, but which has a name similar to another known
variable. You should verify that the variable name is spelled
correctly.</p>
<p>Note: This error only triggers for environment variables (all
uppercase variables), and only when they have names similar to another
known variable in the script. If the variable is script-local, it should
by convention have a lowercase name, and will in that case be caught by
[SC2154] whether or not it resembles another name.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>If you've double checked and ensured that you did not intend to
reference the specified variable, you can disable this message with a <a
href="directive.html">directive</a>. The message will also not appear for
guarded references like <code>${ENVVAR:-default}</code> or
<code>${ENVVAR:?Unset error message here}</code>.</p>
